Over the last couple of year, the expansion of Web
services has grown drastically. In practical applications,
many uncertain attributes of web service change as the
complexity of the Web evolves and influence the QoS
(quality of service). However, existing matchmaking
models and algorithms do not take the uncertain
attributes into account, which leads to inaccurately
matched results.This paper presents an uncertainty-aware
QoS match-making model, UQoSMM, which describes
the uncertainty of QoS attributes under different
conditions. This paper also proposes a QoS decision
making model based on the non-parameter-test,
NPTQOS. The decision making model includes a QoS
stability comparison algorithm according to the history
values of QoS attributes. A prototype has been designed
to realize the uncertain attribute-based Web service
selection.
